Federal prosecutors today announced the indictment of a Long Beach man accused of meeting women on Craigslist in order to force them into being his prostitutes.

Roshaun Nakia Porter, who also goes by Kevin, operated a prostitution ring in Orange County -- and filled its ranks by luring vulnerable women into relationships with him, then threatening them and their families -- according to a government press release.

Porter, 36, allegedly met the women by placing ads on Craigslist and SeekingArrangement.com. He let them believe he was interested in a normal monogamous relationship, then pressed them into becoming sex traffickers, prosecutors say.

He was arraigned Monday in federal court after being indicted by a federal grand jury. Porter is charged with two counts of sex trafficking by coercion and two counts of forced labor, and faces life in prison if convicted.

The Santa Ana Police Department arrested Porter on April 10 following a sting conducted by its Special Investigations-Vice Unit. During the sting, authorities said, Santa Ana detectives encountered five women who said Porter was forcing them to be his prostitutes.

According to a federal criminal complaint, “Porter charged his customers between $100 for 15 minutes to $300 for 60 minutes for illicit sex, and that all of the proceeds were provided by the victims to Porter. Additionally, Porter threatened victims by telling them that if they tried to leave, he would find them and hurt their families.”

Before police rescued them, the women lived and worked for Porter out of hotels in Orange County, according to the complaint.

Porter is being held without bail. A criminal trial is scheduled to begin June 19.

Anyone with further information about Porter or his alleged victims is asked to call the FBI at (310) 477-6565 or the Santa Ana Police Department at (714) 245-8501.
